How NOT to fix a Karcher Pressure Washer

It really wasn't that broken, it just makes noise when it's not suppose to. Now it's really broken.
I watched some other videos and I didn't have a leak but I have a intermittent motor noise. Someone stated they spent $75 on a housing and $45 on other parts, well that's $120 bucks without a guarantee that anything will fix the problem. I would put that money towards a nicer bigger gas machine...
